XXH3 is the faster alternative to XXH64 which utilizes SIMD
when hashing large chunks of memory and similar mixing to
WyHash (64x64 -> 128 mul) for smaller inputs.

An embedded manifest file is really just XML data embedded as a RT_MANIFEST resource (ID = 24). Typically, the Windows-only 'Manifest Tool' (`mt.exe`) is used to embed manifest files, and `mt.exe` also seems to perform some transformation of the manifest data before embedding, but in testing it doesn't seem like the transformations are necessary to get the intended result.
So, to handle embedding manifest files, Zig now takes the following approach:
- Generate a .rc file with the contents `1 24 "path-to-manifest.manifest"`
- Compile that generated .rc file into a .res file
- Link the .res file into the final binary
This effectively achieves the same thing as `mt.exe` minus the validation/transformations of the XML data that it performs.
How this is used:
On the command line:
```
zig build-exe main.zig main.manifest
```
(on the command line, specifying a .manifest file when the target object format is not COFF is an error)
or in build.zig:
```
const exe = b.addExecutable(.{
.name = "manifest-test",
.root_source_file = .{ .path = "main.zig" },
.target = target,
.optimize = optimize,
.win32_manifest = .{ .path = "main.manifest" },
});
```
(in build.zig, the manifest file is ignored if the target object format is not COFF)
Note: Currently, only one manifest file can be specified per compilation. This is because the ID of the manifest resource is currently always 1. Specifying multiple manifests could be supported if a way for the user to specify an ID for each manifest is added (manifest IDs must be a u16).

SPARCs have delayed branches, that is, it will unconditionally
run the next instruction following a branch.
Slightly reorder the _start code sequence to prevent it from
accidentally executing stray instructions, which may result in odd
program behavior.
`ContainerDeclarations` is an abstraction of `ContainerDeclaration*`.
Removing this abstraction allows the `ContainerMembers` rule to contain
more concrete information without having to look at the definition
of `ContainerDeclarations`.
When `std.mem.indexOf` is called with a single-item needle, use `indexOfScalarPos` which is significantly faster than the more general `indexOfPosLinear`. This can be done without introducing overhead to normal cases (where `needle.len > 1`).
* fs/test.zig: use arena allocator more consistently
* fs/test.zig: remove unnecessary type information
Zig can (now?) implicitly cast a `&.{ "foo"}` when passed to
`fs.path.join()`, so the `[_][]const u8` is unnecessary.
* fs/test.zig: Use fs.path.join() for longer paths
Replace long path constructions (that use several "++ path_sep ++")
with a single call to `fs.path.join`. Seems more readable to me.
* fs/test.zig: fmt
* add Module instances for each package's build.zig and attach it to the
dependencies.zig module with the hash digest hex string as the name.
* fix incorrectly skipping the wrong packages for creating
dependencies.zig
* a couple more renaming of "package" to "module"
Finish the work started in 4c4fb839972f66f55aa44fc0aca5f80b0608c731.
Now the compiler compiles again.
Wire up dependency tree fetching code in the CLI for `zig build`.
Everything is hooked up except for `createDependenciesModule` is not yet
implemented.
* start renaming "package" to "module" (see #14307)
- build system gains `main_mod_path` and `main_pkg_path` is still
there but it is deprecated.
* eliminate the object-oriented memory management style of what was
previously `*Package`. Now it is `*Package.Module` and all pointers
point to externally managed memory.
* fixes to get the new Fetch.zig code working. The previous commit was
work-in-progress. There are still two commented out code paths, the
one that leads to `Compilation.create` and the one for `zig build`
that fetches the entire dependency tree and creates the required
modules for the build runner.
